In an old text,which I cannot locate, they advised burning scrap paper,
treating the ash with nitric acid, and recovering silver nitrate from the
solution.
I think the same text explained how to manufacture pyrogallic acid from oak
galls.
I have done neither, and cannot comment on the health implications of carrying
out either.
All the best
